Afroablepharus wahlbergi, Smith, 1849.

It's been longer than I intended; you see, for a couple of weeks, the only pictures I've been wanting to post have been ones of reptiles and amphibians from Lusaka. Which could turn into a bit of a tiring tour of (non-avian) reptiles and amphibians from Lusaka.

Today I had a revelation - it's my blog; it's my decision if I want to occasionally focus on a particular group for a period of time. And as I'm feeling more than a little bit homesick of late, meet today's guest:

 Yes, by the way, that is a lizard perched entirely upon the distal phalanx of a human finger. Here's another picture:


The phalanx in question is approximately 28 millimetres long, so this little customer was a touch over three centimetres including tail, probably just pushing 15 millimetres snout-to-vent length (a standard length measurement for a lot of reptiles). 

It's probably important to note that this isn't an adult. The adults are relative giants, at about the length of an entire finger.

These titchy little Buluzi (remember that generic Chewa word for lizard from this post on Trachylepis striata wahlbergi?) are most commonly noticed as a frantic rustly and a silver squiggle in leaf-litter; although they do have reasonably robust legs, they can escape predators much more effectively by swimming through their rotting playground than they can by running through it.

We'll attempt a translation of their English name to Chewa as Buluzi ndi Maso wa Njoka; paying even less heed to grammatical differences between English and other languages, that could be Njoka-Diso Buluzi.

It's probably easier to tell you that this is, to the English speaking world, a snake-eyed skink, specifically Wahlberg's Snake Eyed Skink. Yes, Wahlberg does pop up a lot in African herpetology.

Perhaps more universally (overlooking uncertain generic placement), it's binomial name is:

Afroablepharus wahlbergi
(Smith, 1849) 

or sometimes 

Panaspis wahlbergi
(Smith, 1849)
 
As I mentioned, the adults are most commonly noticed as they flee through the ground-cover at high speed, and as they are small, well hidden and not given to sticking around when something large approaches, can be difficult to photograph, even when they stop to peer back at the intruder through the leaflitter:

They're called snake-eyed skinks, by the way, because they lack a moveable upper eyelid; like snakes, and the majority of geckos, they can't blink.
